Temperature control

Always the right temperature

The TRUMPF temperature control registers the intensity of the thermal radiation on the component surface and controls the laser power based on the set nominal temperature. When used in laser plastic welding and laser case hardening, it ensures consistent results – even when working with complex component geometries. When used with a scanner, the temperature controller is integrated directly into the electronics of the PFO. The pyrometer also sits directly on the optics – external units are not necessary. There is a compact control box included in the scope of delivery with the fixed optics.

Direct coupling of the pyrometer to the optics and parameterization using TruControl.

Full transparency

Guaranteed traceability due to stored temperature data.

The trend at a glance

You can use the trend indicator to detect slow divergence of the process at an early stage.

Laser plastic welding supported by the pyrometer.

Laser plastic welding using the quasi-simultaneous method

With the TRUMPF temperature control you can weld plastic housings or plugs of electronic control units, sensors, and actuators with high-quality welding and a tight seal. Impurities or higher glass fiber content in the laser-transparent upper part are quickly detected due to their deviating temperature behavior.

Laser plastic welding using the contour method

In contour welding, the component is rotated under the fixed laser beam. The temperature control ensures a consistently high heat input across the entire seam point.

Laser case hardening

The temperature control for laser case hardening regulates the laser power in a spatially resolved manner. This enables a build-up of heat on the edges, holes, or corners of components to be avoided.

Temperature control for laser plastic welding

The TRUMPF temperature control for laser transmission welding of plastics measures the temperature of the joining zone with a pyrometer. The system registers the intensity of the thermal radiation in a pre-determined wavelength spectrum and regulates the laser powerto the nominal temperature. Typical applications are the quasi-simultaneous welding of closed contours with scanner optics and the contour welding of round parts with fixed optics.

Temperature control for laser case hardening

In the case of laser case hardening, the pyrometer measures thesurface temperature during the hardening process andregulates the laser power in a spatially resolved manner. This makes it possible to avoid a build-up of heaton the edges, holes, and corners of the components andto achieve a uniform hardness depth at a defined degree of hardness. Byusing the scanner optics, you can harden all manner ofgeometries. And with the oscillating laser beam,you can even produce varying track widths.
